A nurse measures the temperature of a patient to be 40.7°C
(a) What is this temperature on the Fahrenheit scale?
°F
(b) Do you think the patient is seriously ill? (Assume the patient has a serious fever if the temperature is above 100°F.)
Yes
No
Explain
In everyday experience, the measures of temperature most often used are Fahrenheit F and Celsius C. Recall that the relationship between them is given by the following formula.
F = 1.8C + 32
Physicists and chemists often use the Kelvin temperature scale. You can get kelvins K from degrees Celsius by using the following formula.
K = C + 273.15
(a) Calculate that value.K(25) =
(b) Find a formula expressing the temperature C in degrees Celsius as a function of the temperature K in kelvins.
C =
(c) Find a formula expressing the temperature F in degrees Fahrenheit as a function of the temperature K in kelvins.
F =
(d) What is the temperature in degrees Fahrenheit of an object that is 272 kelvins?
Temperatures in Biomedicine.
(a) Normal body temperature. The average normal body temperature measured in the mouth is 310 K. What would Celsius and Fahrenheit thermometers read for this temperature?
(b) Elevated body temperature. During very vigorous exercise, the body’s temperature can go as high as 40OC. What would Kelvin and Fahrenheit thermometers read for this temperature?
(c) Temperature difference in the body. The surface temperature of the body is normally about 7CO lower than the internal temperature. Express this temperature difference in kelvins and in Fahrenheit degrees.
(d) Blood storage. Blood stored at 4.0OC lasts safely for about 3 weeks, whereas blood stored at -160OC lasts for 5 years. Express both temperatures on the Fahrenheit and Kelvin scales.
(e) Heat stroke. If the body’s temperature is above 105OF for a prolonged period, heat stroke can result. Express this temperature on the Celsius and Kelvin scales.
